An 1800-kg truck pulls a 710-kg trailer away from a stoplight with an acceleration of 1.20 m/s2 . Part A What is the net force e

faust18 [17]

Answer:

F = 852 N

Explanation:

We apply Newton's second law to the trailer :

F = m*a Formula (1)

F : net force exerted by the truck on the trailer Newtons (N)

m : mass of the trailer in kilograms (kg)

a : acceleration of the trailer in meters over second square (m/s²)

Data

a=1.20 m/s² : acceleration of the trailer

m=710 kg : mass of the trailer

We replace data in the Formula (1) to calculate the net force exerted by the truck on the trailer

F = (710 kg)*(1.20 m/s²)

F = 852 N

Consider (a) an electron (b) a photon, and (c) a proton, all moving in vacuum. Choose all correct answers for each question. (iv

Electron, photon and proton carry momentum .

De Broglie derived the relationship between the wavelength and momentum of matter. This relationship is known as de Broglie's relationship.
De Broglie's relationship is given by $\lambda=\frac{h}{mv}$ ...(1)
Momentum is the product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.

Equation (1) can be written as $\lambda=\frac{h}{p}$ where λ is known as de Broglie wavelength and p is momentum , h = Plank’s constant

For photon , the momentum is given by $p=\frac{E}{c}$ ...(2) where c is the speed is the speed of light .

From equation (1) and (2) we can conclude that electron, photon and proton carry momentum .

What is the magnitude of g at a height above Earth's surface where free-fall acceleration equals 6.5m/s^2?

Tom [10]

The magnitude of 'g' at a place is expressed in terms of
the acceleration due to gravity.

You have said that the gravitational acceleration at that place
is 6.5 m/s². So THAT's the magnitude of 'g' right there.

Based on the given information, the type of boundaries these two new plates would share with each other and the Arabian Plate are divergent boundaries.

<h3>Who are geologists?</h3>

A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other planets.

Geologists have observed that a portion of Africa is breaking away from the main continent. This is happening because the African Plate is in the process of splitting up into two parts. Scientists have named the two new tectonic plates the Nubian Plate and Somalian Plate. Both of these plates are not only moving away from each other but also away from the Arabian Plate.

There are 3 types of boundaries.

At convergent boundaries, the two tectonic plates comes closer to each other.

At divergent boundaries, the plates move away from each other.

At transform boundaries, the plates are moving parallel to their boundary.

Based on this, all boundaries will be divergent boundaries.
